Adjustable Ball Lock Pins can be used for clamping, or simply to provide a variable grip length.
Grip length adjusts +/- 1/4" from nominal.
Four balls are standard on Adjustable Ball Lock Pins to provide more-distributed ball-pullout force in clamping applications.
| New Design for Greater Clamping Strength!
FEATURES: These Ball Lock Pins have an adjustable grip length. They can be used for clamping, or simply to provide a variable grip length. The threaded handle turns to provide a +/- 1/4" clamping range or adjustment range. When used just for variable grip length (not for clamping), the handle can be secured with the supplied knurled locknut. These single-acting pins are manufactured with four balls as standard, instead of two, for more-distributed ball-pullout force in clamping applications. Available in steel or stainless steel. Patent no. 3,101,641. Made in USA.
SIZES: Choice of three handle styles: Knob, T, and L. Available for the following pin diameters, each in a choice of many standard grip lengths — see Dimensions page for part numbers:
Available from stock only in the standard grip lengths listed. Other grip lengths are available as specials (extra charge and longer delivery time).
